At least one carbon monoxide (CO) alarm is a requirement on nearly all private and non-private boats in scope of the Boat Safety Scheme (BSS) Requirements. BSS Certifications will not be issued to boats without alarms.

The requirements apply to boats with permanent accommodation, which is defined in this way:

“Space surrounded by permanent boat structure in which there is provision for any of the following activities: sleeping, cooking, eating, washing/toilet, navigation, steering. Spaces intended exclusively for storage, open cockpits with or without canvas enclosures and engine rooms are not included.”

There are four new BSS Check items in the BSS examination:

Check 6.4.1 covers the provision of alarms in suitable numbers – this check ensures everyone on board can hear the alarm if it activates.

Check 6.4.2 is an Advice check for private boats, promoting a CO alarm in the same space as a solid fuel stove – stoves can present a specific risk if flue gases enter the cabin.

Check 6.4.3 requires CO alarms to be placed in open view, be of a certified quality and have a test function button – this check provides an assurance about the quality of alarm manufacture and performance.

Check 6.4.4 requires CO alarms to be in good and working condition, showing no signs of damage, being within any visible expiry dates and passing the function test using the test button – this check ensures the alarm will work effectively if called upon.

There is a handout available as an essential guide to all the new requirements and background information. It covers what is required and how the checks will be carried out by BSS Examiners and how the alarms will help keep crew members safe. Click on this link to download it.
